2.8.7. Probe calibration : important advance information
The original pH probe provided is already calibrated. It is, therefore, not necessary to calibrate the pH probe when
putting the equipment into service for the first time.
I
However, it is essential the pH probe be calibrated at the beginning of each season when returning to service,
and after each probe replacement.
2.8.8. Calibrating the pH probe
1) Open the pH 7 and pH 10 calibration solutions (use only single-use calibration solutions).
2) Turn off the filtration (and therefore the electronics unit).
3) If the probe is already installed:
a) Remove the probe from the probe holder, without disconnecting it.
b) Remove the probe holder nut and replace it with the stopper provided.
If the probe is not already installed:
Connect the probe to the electronics unit.
4) Turn on the electronics unit.

Insert the probe into the pH 7 calibration solution, then wait a few minutes.
Do not touch the probe.
a) Rinse the probe under running water, then leave it to drip-dry without wiping it.
b) Insert the probe into the pH 10 solution, then wait for a few minutes.
Do not touch the probe.
a) Rinse the probe under running water, then leave it to drip-dry without wiping it.
b) Install the probe into the probe holder.
Repeat the operation following the above instructions, several times if necessary.
If calibration still fails, replace the probe then perform another calibration.
